Zanzibar is a tropical island with a warm and humid climate throughout the year, so lightweight and breathable clothing is recommended. Here are some suggestions for what to wear as a tourist in Zanzibar:

1. Loose, comfortable clothing: Opt for loose-fitting clothing made of lightweight materials such as cotton or linen. This will help keep you cool and comfortable in the warm and humid climate.
2. Swimwear: Since Zanzibar is an island, you’ll likely be spending time on the beach or in the water. Make sure to pack some swimwear, including a swimsuit, cover-up, and flip-flops.
3. Sun protection: Zanzibar is located near the equator, which means the sun is strong and can easily burn your skin. Bring a hat, sunglasses, and sunscreen with a high SPF to protect yourself from the sun.
4. Comfortable shoes: You’ll likely be doing a lot of walking around Zanzibar, so it’s important to bring comfortable shoes. Sandals or sneakers are a good option.
5. Modest clothing: While Zanzibar is a tourist destination, it’s still a conservative Muslim society. It’s respectful to dress modestly when you’re in public places. Avoid shorts, short skirts, and revealing tops.
6. Lightweight jacket: Although it’s generally warm in Zanzibar, it can get chilly in the evenings. Bring a lightweight jacket or sweater to keep you warm.

Overall, remember to dress comfortably, modestly, and appropriately for the weather and culture in Zanzibar.
